Ancient fish fossils were discovered 24.4 billion years ago, what did the fossils look like?

Ancient fish fossils were discovered 100 million years ago On May 19, the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences announced that its research team in Xu Guanghui found a new large ancient fish fossil in Luoping, Yunnan Province. Recent research suggests that the fossil is a new species of the genus Pteryth, a radial-finned fish, and the largest known basal radial-finned fish predator in the Luoping biota hundreds of millions of years ago.

Fossils are the remains, ruins, or remains of paleontology left in the rocks. The most common fossils are bones and shells. The study of fossils can understand the evolution of organisms and help determine the age of strata.

The remains of ancient animals or plants preserved in the rocks of the earth's crust or evidence indicating the existence of the remains are known as fossils.

So, how are fossils formed?

During the long geological ages, countless creatures lived on the earth, and many of their corpses or traces of life were buried by the sediment of that time. In the years that followed, the organic matter in the remains of these organisms was almost decomposed, and the hard parts such as shells, branches and leaves, etc. They were petrified into stone along with the surrounding sediments, but their original shape and structure (and even some subtle internal structures) remained.

In the same way, the traces left by living organisms can be preserved in this way. It usually takes at least hundreds of millions of years for us to fossilize these fossilized biological remains and fossilized remains.

Normally soft parts, such as muscles or epidermis, are completely corroded before preservation, leaving only the more resistant parts, such as bones or shells. They are then replaced by the penetration of minerals in the surrounding sediment. Many of the fossils were also flattened by the weight of the rock that covered them.

Simply put, fossils are "stones" made from the remains or remains of organisms that lived in the distant past.

In the years that followed, the organic matter in these biological remains was completely decomposed; In the same way, the traces left by living organisms can be preserved in this way. We call these fossil biological remains and remains fossils.

Well, that's all for this issue.

In fact, it is the appearance of the stone, but there are some bodies of some animals in the stone, and you can see the state of this animal.

The appearance of fossils is a process of osteopetrification that maintains the bone or tooth structure of the original organism. The fossils of ancient fish here are about 5m to 10m long. It also maintains the symmetrical spine-like skeleton of the current fish.

It is a very large fish fossil, and this fossil is also very precious, a new species, which is very interesting for research.

Fossils are some ancient plants or organisms that have evolved slowly, and they are also very beautiful.

On May 19, 2021, the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences released a message on its official website saying that the research team of the Institute found a large ancient fish fossil in the Luoping area of Yunnan Province, so what are the characteristics of this fish fossil? Let's take a look. <>

According to expert research, the ancient fish fossils found this time have a historical evolution process of 100 million years, scientifically known as "Zhang's wing cod", it is about 30 centimeters long, with a large mouth and sharp teeth. It has a streamlined body and is a swift predator, feeding on small ancient invertebrates or plankton. At present, only 5 pieces of this fossil have been found in China, so it is also very precious.

Experts say the fossil belongs to the radial-fin species, which is the largest known in the paleontology of the Triassic period. <>

It is reported that the reason why the scientific community calls this kind of fossil "Zhang's wing cod" is to commemorate the paleontologist Academician Zhang Miman, who has made significant contributions to the study of paleontology in China. In addition, the discovery of ancient fish fossils has also attracted the attention of many science enthusiasts, combined with other paleontological fossils found in Yunnan over the years, in the early Middle Triassic of China, a very mature and complex biological ecosystem has been established in South China Sea.

About 100 million years ago, ray-finned fish began to land on the continent and gradually evolved into terrestrial organisms, including humans, while those fish that did not come ashore have been baptized by nature for hundreds of millions of years, and have gone through vicissitudes of life, and continue to radiate and evolve into a variety of new marine species. <>

The earliest recorded discovery of radial-finned fishes was in the marine environment near Madagascar and Europe and North America, and is recognized by the scientific community as an iconic species of the Early Triassic period. The discovery of this fish provides important evidence for the evolutionary history of radial-finned fishes in Asia, which is of self-evident significance in paleontological research.

With a body length of 26 centimeters, it represents the oldest fossil evidence of the colodontidae family, and it is also the first time that the genus Explosive Fish has been discovered in Guizhou. The discovery and study of Panzhou Popfish have revealed the ecological adaptation diversity of the previously unknown colodontidae, and updated people's understanding of the recovery of the Triassic marine ecosystem.

Large, new, etc. It is large in size and is the largest fish of this type in the Luoping biota; It is a new species, a new species of the genus Wing Cod, a radial-finned fish.

Scientists found hundreds of millions of years ago ancient fish fossils, the fossil fish is characterized by: body size is about 30 centimeters long, with large mouth fissures and sharp teeth, and the body size is streamlined, is a fast-swimming predator, belongs to vertebrates, the fossil is a new species of radial-finned fish wing cod, belongs to a large ancient fish fossil, radial-finned fish are divided into three groups: cartilage hard scale appendage, whole bone appendage and true bone appendage.

It is an ancient vertebrate with a body length of about 30 centimeters, sharp teeth, and a fast-swimming predator, and the fossil is a new species of the genus Pterygophod, a radial-finned fish, and the largest known basal radial-finned fish in the Luoping biota hundreds of millions of years ago.

Fish fossilized jade. There are all kinds of wonders in the world, and I have an expert's treasure, which is this fish fossil, petrified jade. The fish fossil is 9 cm long, 10 cm wide, 5 cm high, and 19 cm in diameterWeight 378 grams, the fish is 15 cm long and 3 cm wide.

Recently, scientists have discovered fossils of ancient fish from 100 million years ago. The research team named the fossil of the new genus "Zhang's pterocarpus", which was intended to be dedicated to his mentor, Academician Zhang Miman. The discovery of "Zhang's pterocarpus" has further increased the scientific understanding of the diversity of pterocarp, combined with the recent discoveries of large marine reptiles and Yunnan tyranny in the Luoping biotaThis indicates that a mature and complex ecosystem has been established in South China Sea in the early Middle Triassic.

In terms of the origin of fossils, fossils are the remains of animals and plants left in rocks. Often, soft parts such as muscles or epidermis are corroded before preservation, leaving only more resistant parts such as bones or shells. They are then infiltrated and replaced by minerals in the surrounding sediment.

Many fossils have been flattened by the weight of the rocks that cover them, and paleontological remains and their organisms are still present in the strata. Secondly, the study of fossils can study the extraction of fossil energy.

The study of fossils can explore the origins, radiation, and extinction events of important organisms in geological history. Although predecessors have done a lot of research work in this field and made many valuable achievements, there are still many unsolved problems in this field. For example, it is unclear that the causes of the five mass extinctions since the Cenozoic Era are analyzed and discussed.

Further research is needed on the discontinuities and differences between the Precambrian Ediacaran fauna and the Cambrian fauna. There is still no final answer to the dispute between "Chinese dragons and birds" and "Chinese birds and dragons". Therefore, there is still a long way to go in studying paleontological fossils.

The study of fossils can study the evolution of the environment and is instructive for reality. The paleoecological study of fossils is an important basis for reconstructing paleogeography and paleoclimate in geological history. Every living thing is the result of living in a certain environment and adapting to it.

All kinds of living things have characteristics that reflect environmental conditions in their habits, behaviors, and body morphology.

It's great to study some animals, and it will make me humans better at studying animals, and it can enrich human knowledge.

The purpose of studying fossils is to help people understand the history of the past and thus reveal the history of human development.

The study of fossils allows people to understand history, but also to understand some biological issues, and it can also provide people with some professional knowledge.

The paleoecological study of fossils is an important basis for reconstructing the paleogeography and paleoclimate of the geohistorical period. Every organism is the result of living in a certain environment and adapting to the environment. Various organisms have characteristics that reflect environmental conditions in their habits, behaviors, and body morphological structures.

In Luoping, Yunnan Province, a research team has found a large fossil of an ancient fish in this place, and after research, it was found that this fish is a new species, 100 million years ago.

The site is in Luoping, Yunnan, and the shape of these fossils is also very peculiar, and it is also a fossil belonging to some fish, which is also of great significance for archaeology.

The Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences announced on the 19th that the research team of Xu Guanghui of the Institute found a new large ancient fish fossil in Luoping, Yunnan.

In Luoping, Yunnan Province, these fossils are a new species of the genus Pterocarpus, which is of great research significance.

The site of these fossils is also the earliest fossil in the world in Yunnan, China, and these fossils are also very peculiar, belonging to the large ancient fish fossils.

Scientists have discovered ancient fish fossils 100 million years ago, what is the significance of this discovery? Recently, scientists have made huge discoveries in fossils, and the fossil masses have found ancient fish fossils hundreds of millions of years ago, and this discovery can be described as shaking the ancient and the present, and the fossils from hundreds of millions of years ago are of great significance for our contemporary people to understand the changes of the earth and understand the habits of previous organisms. The findings of human research have extraordinary significance.

Fossils are the remains, relics, or relics of ancient creatures that are buried in the ground and become stone-like things. In the beginning, people did not pay much attention to fossils, but some experts found the reference significance in them, and fossils have become hot since then, and have become a hot field of research. Studying fossils can help understand the evolution of organisms and help determine the age of strata.

From the fossils, you can see the appearance of ancient animals and plants, so that you can infer the living conditions and living environment of ancient animals and plants, you can infer the age of the formation of the strata where the fossils are buried and the changes they have undergone, and you can see the changes of organisms from ancient times to the present, and so on.

So since then, fossils have become more and more important to geologists. Fossils are mainly found in marine sedimentary rocks, which are formed when sediments such as calcareous soft mud, sand, and shell layers in seawater are compacted and cemented into rocks. Only extremely rare fossils occur in volcanic and metamorphic rocks.

The volcanic rock turned out to be in a molten state, and there was no life in it. Metamorphic rocks are formed by very large changes, so that the fossils in the original rocks are generally wiped out. However, even in sedimentary rocks, only a small fraction of the prehistoric flora and fauna remain.

The older we go back in time, the longer the time interval between the missing fossil record. The older the rock, the more opportunities there are for destructive forces, and the more unrecognizable the fossils become. And because the older organisms were different from today's organisms, it was difficult to classify them.

This situation further complicates matters. However, despite this, the large number of preserved fossils of organisms still provides a good record of our understanding of the past.

At present, fossils are becoming more and more precious, through fossils we can not only see those historical events beyond the present, people, animals and plants, etc., but also fossils also include the unique memory of this rock, in its memory contains the infinite changes of the vicissitudes of this land, which has extremely important reference value, so it has become a popular field of research for many experts at present, seeing the mystery through fossils and discovering history.

This discovery is of great significance, because it can enrich people's understanding of paleontology, further understand the changes of the earth, and understand the historical changes of this type of creature.

"Panzhou Tyranny", it is the oldest fossil of the colodontidae family to date. It is understood that the new discovery of "Panzhou Tyranny" by Chinese scientists and related research results**, published in an international academic journal** on April 7, revealed the ecological adaptation diversity of the mute fish family that was unknown in the past, and also updated people's understanding of the recovery of the Triassic marine ecosystem.

The discovery can be described as shaking the past and the present, and the fossils from hundreds of millions of years ago are of great significance for our contemporary people to understand the changes of the earth and the habits of previous organisms. The findings of human research have extraordinary significance.
